LOI Review vs. Full Due Diligence
Two different analyses. Two different stages. Both protect your investment, but they answer fundamentally different questions.
LOI Review vs. Due Diligence: An LOI review is a focused legal analysis of deal terms before a buyer commits to exclusivity and due diligence costs. Due diligence is a comprehensive investigation of the target company conducted after LOI signing. LOI review takes 24-48 hours and evaluates deal structure and negotiation position. Due diligence takes 4-8 weeks and evaluates the business itself. Both are essential. Neither replaces the other.
Side-by-Side Comparison
Understanding when each analysis applies and what it covers.
| LOI Review | Full Due Diligence | |
|---|---|---|
| When | Before signing the LOI | After LOI is signed |
| Duration | 24-48 hours | 4-8 weeks |
| Focus | Deal terms and structure | The business itself |
| Key Question | "Should I commit to this deal on these terms?" | "Is this business what the seller says it is?" |
| What It Covers | Purchase price structure, binding provisions, exclusivity, termination rights, risk allocation | Financials, contracts, litigation, IP, operations, customers, regulatory |
| Deliverable | Redline markup + risk memo + strategy call | Executive summary, red flag analysis, valuation impact |
| Cost Exposure | Low (review only) | High ($25K-$100K+ in professional fees) |
Why LOI Review Comes First
Once you sign the LOI, you enter exclusivity. The clock starts. Every dollar spent on due diligence increases your switching cost.
Problems found during due diligence are harder to negotiate because you have already committed time and money. The seller knows this. Your leverage decreases with every week that passes.
LOI review catches structural problems before you are locked in. Unfavorable exclusivity terms, binding provisions you did not realize were binding, missing termination rights. These are issues that shape the entire deal, and they are far easier to address before signing.
Think of it as qualifying the deal before you invest in investigating it.
What LOI Review Catches
Issues due diligence cannot address
- Unfavorable exclusivity terms that limit your negotiating timeline
- Binding provisions you did not realize were binding
- Missing termination rights if due diligence goes badly
- Purchase price structure issues (earnouts, working capital, escrow)
- Vague due diligence access provisions that will slow you down later
What Due Diligence Catches
Issues LOI review cannot address
- Financial irregularities and unsustainable earnings
- Undisclosed litigation or regulatory issues
- Customer concentration risks
- Key employee retention concerns
- Environmental or compliance liabilities
- IP ownership disputes
The Right Sequence
LOI Review
24-48 hours
Evaluate the deal terms. Identify structural risks. Negotiate from maximum leverage.
Sign LOI
Enter exclusivity
Commit to the deal on terms you understand and have negotiated.
Due Diligence
4-8 weeks
Investigate the business. Verify representations. Quantify risk.
Skipping step 1 is the most common mistake buyers make. They sign the LOI, spend weeks and tens of thousands on due diligence, then discover the deal structure was flawed from the start.
"I've seen buyers spend $75,000 on due diligence before realizing the LOI locked them into terms they never should have accepted. A 24-hour LOI review would have caught it. The math is simple.
